I doubt it. I had R's, and they don't get moving too much with rated power. Once impedance rise takes effect, they're not going to be seeing much power at all.
i'd put one amp on each sub @ 1 ohm. box should be 2 cubes per sub, so 4 cubes net total and 34hz is good tuning. either way, as long as the gains are correct you wont have problems with to much power. i will be giving my type r 12's about 3000 watts a piece.
